Performance tuning and ECU mapping

Category: Mechanical repair & servicing

Also known as: ECU remap, chip tuning, injection mapping, dyno tuning, reprogramming

Reprogramming the engine management unit, or building a custom fuel and ignition map, to suit modifications such as an aftermarket exhaust or air filter. Usually measured on a dyno so the result is set against real readings rather than a generic file.
